CLAMP FOR BUNDLlNG CORRUGATED METAL SHEETS 0R PLATES.

SPECIFICATION forming part of Letters Patent No. 670,765, dated March26, 1901.

Application filed February 9, 1900. Renewed February 11, 1901. SerialNo. 46,878. \N d l) To all whom it may concern:

Be it known that I, FRANK G. CALDWELL, a citizen of the United States,residing at Wheeling, in the county of Ohio and State of West Virginia,have invented new and useful Improvements in Clamps for BundlingCorrugated Metal Sheets or Plates, of which the following is aspecification.

The object of my invention is to provide a simple, inexpensive,thoroughly effective,and easily-applied clamp for bundling corrugatedmetal sheets or plates to facilitate the handling and transportation ofsuch plates or metal sheets.

My invention consists in a clamping device preferably having one endportion transversely corrugated to correspond with the corrugations onthe metal sheets or plates that are to be bundled or made into apackage, the said corrugated end portion of the clamp being adapted tofit between a number of corrugated metal sheets or plates at about thecenter of the bundle and the outer end of said clamp beinglongitudinally slitted to provide a plurality of tongues that are to bebent over in opposite directions to clasp firmly against the outer sidesof the bundle of corrugated metal sheets or plates on its oppositesides, as hereinafter set forth.

In the annexed drawings, illustrating the invention, Figure 1 is aperspective of one form of my clamp for bundling corrugated metal sheetsor plates. Fig. 2 is a perspective showing a modified form of said clamphaving only two tongues. Fig. 3 is aview of a bundle or package ofcorrugated metal sheets or plates with the clamps thereon to secure themetal sheets or plates together. Fig. 4 is a sectional view of the same,illustrating the application of the clamps.

The clamp is composed of an oblong metal strip having one end preferablyprovided with transverse corrugations l and the other end longitudinallyslitted to form a plurality of tongues 2, that are adapted to be bentover in opposite directions. The transverse corrugations 1 may occupyabout one-half the length of the metal clamp and should be formed tocorrespond with the corrugations in the metal plates or sheets that areto be bundled together. The tongued end of the clamp may comprise anysuitable number of tongues, some of which are to be bent over in onedirection and the others in an opposite direction when the clamp isapplied toits intended use. In Fig. 1 I have shown the clamp as providedwith three tongues, and in Fig. 2 is shown a clamp having two tongues;but I would have it understood that I do not wish to confine myself toany particular number of tongues, as two or more may be used, aspreferred.

In applying this clamp to its intended use the transversely-coirugatedend portion of said clam p is inserted at any convenient point in theedge portion of the bundle or package of corrugated metal plates orsheets 3, that are superposed one on another. When the clamp is properlyinserted into the bundle or package of corrugated metal plates orsheets, the corrugations 1 of said clamp will fit between and correspondwith the corrugations 4 of said metal sheets or plates,and the tongues 2of the clamp will project beyond the edge of the bundle or package. Oneor more of said tongues will then be bent over the edge of the bundle inone direction and pressed down against the outer side of said bundle orpackage, and the other'tongue or tongues will be bent over in anopposite direction and firmly pressed down against the opposite side ofsaid bundle or package. corrugations l of the clamp being engaged withthe corrugations 4 of the metal sheets or plates it will be impossiblefor the clamp to be withdrawn after the tongues 2 have been bent overagainst the opposite sides of the bundle, and these tongues when so bentover in opposite directions and pressed firmly against the corrugatedmetal sheets or plates will hold said plates or sheets together andprevent one of them slipping on another, thus firmly securing togetherall the corrugated metal sheets or plates in the bundle or package.

The manner of applying the clamp as above described is clearly shown inFigs. 3 and 4 and will be readily understood.

The construction of clamp shown in Fig. 2 is essentially the same asthat illustrated in Fig. 1, but is more inexpensive by reason ofdispensing with the central tongue and also by admitting of the use ofany kind of scrapmaterial to make the same.

By reason of the sive and can be quickly and easily applied to itsintended use.

What I claim as my invention is A clamp for bundling corrugated metalsome sheets or plates, said clamp consisting of a metal strip having oneend portion transversely corrugated to engage between superposedcorrugated metal sheets or plates and. provided at its other end With aplurality of tongues or projections adapted to be bent over the edge ofthe bundle or package in opposite directions, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
